摘　　要：以反渗透海水淡化后浓海水为原料,探究蒸发浓缩过程中常量元素的析盐规律,实验结果表明:浓海水蒸发浓缩过程中常量元素变化规律和海水蒸发浓缩过程中常量元素的变化规律基本一致。利用蒸发浓缩的方式可以从浓海水中依次获取硫酸钙和氯化钠,而镁盐应在析出硫酸钙和氯化钠之后采取沉淀等其他方式获得。In this paper, evaporation and enrichment experiments were carried out to study crystallization law of macro elements from reverse osmosis desalination brine. The results showed that the variation law of macro elements in desalination brine is just the similar with that in normal seawater. Calcium sulfate deposited first and sodium chloride followed during evaporation and condensation experiments. Magnesium salt could be acquired by other methods after the separation of calcium sulfate and sodium chloride.
